Application filed November 16,- 1925. Serial No. 69,424.

Tith my present invention I aim to pro -s vide' a simple, cheap and thoroughly eflicient means for easily expanding or contracting split tire carrying rims and for effectively holding the said rims in either ofsuch positions. It is also my purpose to produce-a mechanism for this purpose which can be easily applied'toany ordinary split tire carrying rim;

I accomplish the foregoing objects and others which willappear as the nature of the invention is better understood-by a construction, combination and operative association of arts, a satisfactory embodiment of which is i lustrated by the accompanying drawings; In the drawings j Figure 1 is a fragmentarycircumferential sectional view through a split: rim illustrating the application of my; improvement thereon] Figure 2 is an inner plan viewthereof.

Figure 3 is a sectional view, similar to' Figure 1, showing the rimcontracted.

Figure 4 1s a View s1m1lar to F1gure8 but showing the intermediate position of the parts in operation. a 7

.7 'Referring now to the drawings in detail, the numerals 1 and 2 designate the ends of a split tire carrying rim. The rim being of metal, embodies an inherent resiliency.

- the rimI rivet or otherwise'secure lugs 3 and t, respectively. The lug 3 is set back "from the end 1, but the lug 4 projects a the outer end portion ofthe lug 3' when the V j j to which such, invention relates. It will be c noted that the improvement may be cheaply suitable'distance beyond the end 2, and this projecting end is preferably widened and 1s centrally bifurcated, as at '5.

the center of the rim ends, and the notch or bifurcation 571s of BQTSIZG to rece ve thereln rim is in normally expanded condition.

Each of the lugs 3 and at is formed with ot 7 that secures on the lug the widened and bifurcated end of aillever 8. The lever is curved in opposite directions from .itsends to a .point adjacent the center thereof, and this portion, indicated for distinction, by the numeral 9, is provided with an eye or opening for the insertion of a pivot 10 that-secures against the sides of the lever 8 links 11. These links are pivotally secured, Qasat 12, to the eye6 of the-lug;- 4. I g

It is to be noted'that the lugsSand i are arranged at The portion of the lever, outward of the pivot 10, 1s rounded'to conform" to the contour of theinner periphery of theriin and lies snugly thereagainst when the rim is-e rpanded,' as clearly disclosed byJFigure 11. of the V drawin s. The lever has its outer end reduced Irom the underrface thereof to provide what I will term a finger13,andpivotally securedon the under or-inner face of the rim section 2, as at let, there is a s'wingable latch 15. The latch is inthe n-ature'of a metal plate which is offset .at the center thereof so thatvthe outer or free end of the. said latch willisnugly underlie the finger 13,

when the latch is swung laterally with, re-'7 I v spect to the rim, for engaging over the finger 13 to retain the lever in;the position illustrated in Figures 1 and 2 of the drawings. ,When it is desiredtovcontract the rim,"- the latch is swung to the dotted line po'sition in Figure 2ofthe drawings and the lever is grasped "and swung first to the po sition illustrated in Figure 4: of thedrawings. lVhen in time position, it will be noted that the rim end 1 is positioned outwardly and disposed slightly spaced from the rim end 2. When the lever is fully swung to the position illustrated in Figure 3 of the drawings-the rim is fully contract-ed and is automatically held'in such condition, incident to the re- On the inner face of the ends 1 and 2 of siliency of the'rim-and the contacting engagementof the fingered end 13 of the lever" 8, with the inner face of'therim section 1.

By returningthe 1e ver; to its initial position the rim will be easily expanded and the rim The simplicity of the construction and the 1 I advantagesthereof, will, it is thought, be fully, apparent to -those skilled'j in the art constructed andmaybe readily applied to i; any-split tire carrying rim and incidentto the purchase obtained by the lever and the links of said lever theriin will be expanded or contracted with a minimum amount'of physical exertion; Ido not, of course,'de

xus r sire to be restricted to the precise details of construction herein set forth and hold myself entitled to such'departures therefrom as fall within the scope of what I claim without I departing from the spirit or sacrificing any of the advantages of the IIIVGIIJCIOD.

Having described the invention, I claim:

1. The'combination with a split tire carrying rim, and lugs secured to the inner face of the ends of said rim, one of-which has a'bifurcated endto receive the confrontlng end of the opposite lug therein, of a lever pivotally secured to one of the lugs and having a pivoted link connection with the second lug. r

2. The combination with the meeting ends of a tire carrying rim, of a means for expanding andcontracting the rim, including I lugs riveted to the inner face of the rim ends,

therein when the rim is in normal expanded condition each i of said'lugs having trans verse inwardly projecting eyes, a lever having a bifurcated end pivotally secured to the eyes of the first mentioned lug, said lever being rounded in opposite directions from its ends to a point adjacent to the center thereof, and having its -free end reduced to provide a finger, links pivotally secured to the juncture of the said rounded portions of the lever and likewise pivotally secured to the eye of the second mentioned lug, and ,swingable latch on the inner face of the rim for engaging the-finger of the lever when the said lever is sw' Lin a ainst the rim. v Y b v In testirn ony whereof I afhX my slgnature.
